LRS Series 3.9 Indoor

The LAMPRO LRS Series is a high-performance LED display solution designed specifically for versatile rental applications such as concerts, festivals, and conferences. It features a modular, easy-handling design where the power supply, HUB board, and receiving card are integrated into a single control box for simplified maintenance. The series offers exceptional creative flexibility, supporting concave and convex arcs, 90-degree round-corner configurations, and both stacking and hanging installation methods. Technical specifications include a high refresh rate of 3840Hz and wide viewing angles, with indoor pixel pitches as fine as 1.9mm and outdoor brightness levels reaching up to 5000 nits. This combination of durability and visual precision makes it a reliable choice for both indoor and outdoor professional event environments.

Questions buyers ask

Before you request a quote

Which pixel pitch do I need?
Divide the closest viewing distance in metres by about 1.2: 2 m away → P1.9, 3 m → P2.5, 4–6 m → P3–P4, roadside → P6–P10. Use the pitch finder on the home page or send us the room and we will shortlist.
Is the price per module, per cabinet or per m²?
Each product page states the unit next to the price. The wall calculator converts it into a supply estimate for your wall size; delivery, structure, processor and installation are itemised separately in the quote.
What content can the screen show?
Anything from a laptop, media player, CCTV or TV box — video, presentations, menus and live feeds — through the video processor supplied with the wall.
How long does installation take?
Most indoor walls up to 10 m² are installed and calibrated in one to two days; outdoor boards depend on the structure and permits. We survey the site first and confirm the schedule in the quote.
What warranty do you give?
Official manufacturer warranty on panels and controllers, serviced by our own engineers in Kathmandu with spares in stock. Warranty terms are itemised in every quote.
Do you deliver and install outside Kathmandu?
Yes. We have installed in Pokhara, Butwal, Bhairahawa, Dang, Dhangadhi, Lumbini and across the valley. Delivery and travel are itemised in the quote.

Tell us the wall.
We'll size the screen.

Share the space and viewing distance — we'll reply with a pixel-pitch recommendation and an itemised quote within one working day.
